LEATHER-SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 515,614, dated February 27, 1894.

Application filed July 28, 1893. Serial No. 431,751. (No model.)

To @ZE whom t may concern:

Be it known that I, SIMON ROSS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Leather-Shaping Machines, of which the following is a specification.

The object ot my invention is to provide a machine for shaping leather into irregular forms, on the principle of the well known Blanchard lathe. I have shown it as primarily adapted for shaping shoe soles, but it is equally adapted to shaping other irregular forms such as shoe heels, brush backs, blinkers for bridles, and various other articles of manufacture.

The various features ot my invention are fully set forth in the description of the accompanying drawings making a part of this specioation, in which- Figure l isa top plan view of my machine. Fig. 2 is a plan view on line fum, Fig.3. Fig. 3 is a side elevation of the machine. Fig. 4 is an end elevation of the machine and jack. Fig. 5 is a perspectiveview of the jack. Fig. 6 is a sectional elevation of the cutter head and guard. Figs. 7 and 8 are diagrams illustrating the method of cutting shoe soles. Fig. 9 is a sideelevation showing a modified form of jack. Figs. 10 and 11 are detail views of Fig. 9.

A represents the base of the machine; B, ahollow column mounted thereon; C, a table mounted upon said column; D, brackets mounted on the opposite end of base A in which the driving shaft E is jonrnaled.

F represents the driving pulley on the shaft E which receives power by a belt from any4 appropriate driver.

G represents a pulley on one end of the drivingshaftE for driving the cutter shaft H.

I represents a pulley also on the shaft E for driving the blower K.

L represents a post mountedV upon one of the brackets D for supporting a supplemental table a.

H represents a vertical cutter shaft supportedin bearings 1, 2.

3 represents a cutter head which is constructed substantially asshown in Letters Patent No. 489,876, granted me January 10,

4 represents a cutter guard carried by the lower end of a vertical shaft 5 that is journaled in a sleeve 6 connected with a sleeve 7 mounted on a vertical shaft 8 that is snpported in a bracket 9 with which the table C is provided.

10 represents a lever the forked end of whichengages with the pin on sleeve 6; it is operated by the chain 11 which passes over crank e and thence to foot lever 12 which is depressed to raise the guard 4, exposing more or less of the cutter head 3.

13 represents a blower pipe the open mouth of which is opposite the cutter head 3; this blower pipe is detachably connected to the table which is pierced with an orice 14, as shown in dotted lines Fig. l. 15 represents a set screw for holding said blower pipe in position. I have shown the point of shaft S as stepped in the top of the blower pipe 13 to assist in holding it in position.

16 represents the opening in the hollow column B. 17 represents a branch pipe connecting said hollow column with the blower K. By means of the arrangement of these parts the dust and shavings are drawn ott the table and away from the knife through the hollow column and the blower.

One of the primary objects of my invention is to provide a horizontally movable jack carrying clamping plates; said jack rests loosely on the table and is manipulated by the operator for reducing the stock.

In Figs. 4 and 5 Ihave shown the preferred construction of jack which consists in a broad base N, sectional arms O, P, at top and .bottom, brace Q connecting said arms, and the clam-ping plates R R', said clamping plate R swivels in the arm O, and clamp plate R swivels on the point of screw S, which engages in the nut in the arm P. T represents a secondary brace connecting the arms O,P. U represents a handle fixed in the base of the jack to enable the operator to move the same uponA the table at will.

In Figs. 9 and 10 I have shown another form of jack in which the base and upright are made of cast metal and the arms O, P, are made integral with the shank Vaand bolted to the upright W, and base Y. I do not wish to limit myself to the sectional stock jack eX- cept in the clauses of the'claim where the sec- ICO tional form lis made an element. 18 represents a gage frame rigidly secured to the table C; it is slotted to receive the slides 19. 20 represents rclamping screws; rrepresents screws the points of which project through the slides 19 and serve as guides for'centering the stock. By loosening the screws 2O the slides 19 may be adjusted to or from each other to suit different sizes of stock. -21 represents a slide on the end of the lgage 22. 23 represents ya clamping screw by which the slide y21 is adjusted laterally to and from the frame 18 to tit different sizes and widths of stock. f

Mode of operation: The pattern is placed uponk the clamp R', the usual spacing plate is placed on the pattern and the stool; is placed thereon; itis centeredA by means ot the gage, as shown in Fig. 1; the upper clamp R is then placed on top of the stock and the screw S turned to clampit. The clamp plates carrying the stock are then turned so as to rest against the brace Q, as shown in Fig. 7; the cutter guard 4 is raised bythe foot treadle 12 yhigh enough to receive the stock between the guard. and cutter disk; the guard is then releasedand the jack moved, the pattern bearto the cutter.

ing against the form h, to present the stock By manipulating the jack the stock will be first trimmed from the point c to point 15k-the jack is then moved away from rthe cutter and the iclamps turned'on the swivel until the `opposite side atfthe heel 1s brought against-the brace Q, as shown in 8, when itl is again presented to the knife and the remaining portion of thestock trimmed away. I have shown the machine as adapted to turn shoe soles, butin trimming heels and blinkers the entire round portion 0f the cut may be taken without adjusting the clamp plates. By employing a vertical cutter head, andjack carrying clamps, moved horizontally upon a table, several advantages are obtained; first, the clamps and pattern are brought close to the operator who overlooks the jack and readily adjusts the stock to the pattern; second, the horizontal table on which the parts are mounted is convenient to hold the stock, pattern, forms, dre., so that the work is more convenient to the operator than with a horizontally arranged cutter head and a vertical jack; third, the stock is trimmed solely by the manipulation of the jack in the hands of the operator who presents the stock to the cutter at the appropriate speed for proper reduction, so that small stock may be trimmed much more rapidly than larger stock; fourth, by employing the brace Q the stock may be supported at two points, namely, by the pattern t resting *against the form h, and by the pattern or stock resting against the brace Q, thereby holding the stock firmly to the action of the knife and avoiding tremor of the clamps due tothe vibration of the rapidly revolving knife when the pattern alone is used as a guide and support. Vibration sometimes causes the knife to dig in and spoil the stock, but by means of the support provided in my jac this is entirely avoided. f f I have shown the clamping device for holding the articles rigidly between the clamps as composed of a screw which is the simplest and best, but I do not desire tovlimit myself to this particular clamping. mechanism except where the same is made a specific element by the terms of claims herein. It will be vobserved that the base of the jack at the forward end is enlarged so as to be very wide rjustin rear of the clamps, by means of which the jack is maintained inr perfect horizontal plane, and is not inclined tobe tilted by the operator sliding it over the table'to present the stock to the cutter in varying curves andA angles.

, Having described my invention, what I claim is- 1. The combination with a leather shaping machine containing lthe table @,and the vertical cutter-head rotating above the table, of a jack resting upon a plane baseindependent yofthe table and free to move in all directions 2.
